The Ship That Broke in Half at Sea
About this video
Discover why a modern bulk carrier can snap in half without a single wave crashing over its deck. This visual essay explains how wave-induced hull flexing, hogging and sagging, silently stresses the ship's structure until the steel gives out, leading to catastrophic failure in calm seas.
